Professional bulk handling – Turnover up to 1000 t per hour
The powerful hydrostatic transmission and advanced Liebherr electronics ensure short, productive working cycles
during bulk handling.
• During grab operation, hoisting, slewing, and luffing are
driven simultaneously at maximized speed to achieve the
highest (possible) turnover.
• During grab filling, features such as automatic lowering and
hoisting guarantee the optimum filling level of the grab.
• The slack rope monitoring system ensures extended lifetime of the ropes and increases operational safety.
• Reverse power is returned to the drive process through
closed loop hydraulics which results in reduced fuel
consumption.
®
• The Cycoptronic
anti-sway system automatically
compensates for all rotational swing, transverse and
longitudinal sway of the load at maximum speeds.
• To provide safe and stress-free working conditions for
®
the operator, Liebherr offers the Cycoptronic
®
Teach-In
feature, a semi-automatic system, which pilots
including
the crane from the vessel hatch to the quay without
any sway. Especially for bulk operation into hoppers,
®
the Teach-In
system increases turnover and ensures
consistent turnover rates during the entire ship unloading.
• Liebherr technology is absolutely resistant to all types of
dust and dirt due to the closed hydraulic system and an
electronic system which is military proven and tested.
• The airflow needed for cooling hydraulic and engine
systems is routed external from the main machinery
house. This helps keep the engine room clean and free
of debris.
